At the annual American Chemical Society spring meeting in 2010, researchers described how active pharmaceutical ingredients (APIs) contained within medications that are applied topically to the skin ... read more

Mercury is naturally present in the earth and enters the air and water through the burning of fossil fuels, discharge of industrial waste, and use of pesticides. Through this redistribution, mercury ... read more

Over the last few years there have been many school and business closures related to mold and bacteria buildup, which have affected the health of the occupants. Mold growth has been potentially linked... read more

The cardinal principle for an operation
involving chemical agents is to limit the potential exposure to a minimum number of personnel, for a minimum period of time, to a minimum amount of the ... read more

Total sulfur and nitrogen (TS/TN) levels are commonly used parameters in the petrochemical, natural gas, and oil refining industries, and the need for their determination is growing due to the ... read more

Energy dispersive X-ray fluorescence (ED-XRF) instruments perform nondestructive analysis of a wide range of elements with accuracy and precision. They are relatively inexpensive and are an excellent ... read more
